Answer 1

Answer:

The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.

The pharynx is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing, and it serves as a pathway for the movement of food from the mouth to the esophagus.

The larynx houses the vocal folds, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus.

The trachea serves as the main passageway through which air passes from the upper respiratory tract to the lungs. As air is pulled into the trachea during inhalations, it is warmed and moisturized before entering the lungs.

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.

The bronchi, singularly known as a bronchus, are extensions of the windpipe that shuttle air to and from the lungs. Think of them as highways for gas exchange, with oxygen going to the lungs and carbon dioxide leaving the lungs through them. They are part of the conducting zone of the respiratory system.

The function of the bronchioles is to ensure that incoming air is supplied to each alveolus. The alveoli are surrounded by tiny blood vessels called capillaries. It is through the thin capillary walls that oxygen enters the blood, and carbon dioxide and water leave the blood.

Alveoli are an important part of the respiratory system whose function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream. These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs.

The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.

Answer 2

Explanation:

Heya!!

Here is your answer!!

The fuctions of various organs are as follows:

1.Nasal Cavity:

• Traps fine dust particles entering through nostrils and allows fresh air to pass to lungs.

2.Pharynx:

• Common passage for food and air.

3.Larynx:

• Contains voice box which helps in sound production.

4.Trachea:

• Possess cartilagenous rings around it.
• Helps to pass air through it.

5.Lungs:

• Lungs helps us in respiration or breathing that is exchange of gases.

6.Bronchi:

• Helps in the passage of air to lungs.

7.Bronchioles:

• Bronchi divides into bronchioles and makes passage for air.

8.Alveoli:

• Gases from lungs are given to blood tissues.

9.Diaphragm:

• Increases or decreases the volume of aboominal cavity during breathing.

Hope it helps u!!
